Recently, some researchers have employed nonbinary measures of successful aging. Little has been done to determine whether these newer measures yield similar findings compared to traditional binary measures. To test for differences, three measures of successful aging were constructed within five waves of the Americans' Changing Lives data set. A number of demographic, behavioral, and psychosocial predictors were used to predict each outcome, examining whether estimates of effect sizes and statistical significance were similar across measures. Although many effect sizes were similar, conclusions regarding statistical significance were inconsistent. For instance, the binary measure downplayed income gradients, the ordinal measure found more racial disparities, and the continuous measure was most likely to detect effects for stressful life events. These differences may be due to the statistical techniques used to handle each outcome. Results imply that uneven application of operationalization approaches may complicate replication efforts, suggesting a need for consistent measurement standards.
最近,一些研究人员采用了非二进制的成功老龄化衡量标准。很少有人确定这些新的衡量标准是否与传统的二进制衡量标准产生类似的结果。为了检验差异,在“美国人生活变化”数据集的五个波次中构建了三种成功老龄化的衡量标准。使用了一些人口统计学、行为和心理社会预测因素来预测每种结果,检验了不同衡量标准下效应大小和统计显著性的估计值是否相似。尽管许多效应大小相似,但关于统计显著性的结论并不一致。例如,二进制衡量标准淡化了收入梯度,有序衡量标准发现了更多的种族差异,而连续衡量标准最有可能检测到生活事件的影响。这些差异可能归因于处理每种结果所使用的统计技术。研究结果表明,操作方法的不均衡应用可能会使复制工作复杂化,这表明需要一致的测量标准。
